Technologies

For Hauck, “best in class” is not about our core technologies, but about the flexibility with which we service our clients and the way we are able to integrate our processes in their supply chain.

Hauck Heat Treatment operates processing facilities in strategic locations around Europe, enabling us to offer all types of heat treatment processes. Our facilities are closely interlinked in terms of logistics, which means that all processes are available to you even if the specific process you seek is not available at the nearest Hauck Heat Treatment location.

At Hauck Heat Treatment we have divided our processes into five core technologies, which are listed below. Selecting a process leads to a description.

Thermal Processes

Hardening and Tempering

Annealing

Sub-Zero

Technology

Hardening and Tempering

Available Hardening and Tempering processes are:

Vacuum Hardening & Tempering

Atmospheric Hardening & Tempering

Induction Hardening

Precipitation / Age Hardening

Aluminium Heat Treatments

Technology

Annealing

Available Annealing processes are:

Full Annealing

Sintering

Stress Relieving

Soft Annealing

Re-crystallisation Annealing

Standardised Annealing

Solution Annealing

Stabilisation Annealing

Magnetic Annealing (Permeable Annealing)

Of course, Hauck Heat Treatment is able to anneal according to your (tailor-made) specifications.

Technology

Sub-Zero

After hardening it may be required to quench materials below 0°C. The required temperature depends on the grade of steel that is used. At Hauck Heat Treatment we have capabilities to cool down up to -160°C. This process can also be used to age specific materials.

Thermochemical Processes

Carburizing

Carbonitriding

Nitriding

Nitrocarburizing

Oxi-Nitrocarburizing

Nitrotec

Stainihard

Stainitec

Technology

Carburizing

Available Carburizing processes are:

Controlled Atmosphere

Low Pressure Carburizing (LPC)

Technology

Carbonitriding

Carbonitriding is a case hardening process which also diffuses nitrogen into the surface with the purpose of increasing hardness and wear resistance.

Technology

Nitriding

Available Nitriding processes are:

Gas Nitriding

Salt Bath Nitriding

Plasma/Ion Nitriding

Technology

Nitrocarburizing

Available Nitrocarburizing processes are:

Gas Nitrocarburizing

Salt Bath Nitrocarburizing

Plasma/Ion Nitrocarburizing

Technology

Oxi-Nitrocarburizing

Oxi-Nitrocarburizing is a nitro-carburizing process that includes a post-oxidation-step to increase corrosion resistance and applies an attractive ‘black’ finishing.

Technology

Nitrotec

The Nitrotec® process is used to enhance the surface and strength characteristics of a range of carbon and low alloy steels. Wear resistance, improved fatigue performance and excellent corrosion resistance are among the properties conferred by this modern surface treatment technology. Such improvements in performance can significantly reduce the manufacturing and materials cost of components, a fact proved repeatedly by the automotive industry on pressed parts.

Technology

Stainihard

Stainihard is a hardening technique that allows for the hardening of the surface of stainless steel without reducing corrosion resistance. The process is based on nitro-carburizing in gas.

Technology

Stainitec

Stainitec is a hardening technique that allows for the hardening of the surface of stainless steel through plasma treatment without reducing corrosion resistance.

Brazing

Vacuum Brazing

Belt Furnace Brazing

Induction brazing

Aluminium Brazing

Technology

Vacuum Brazing

Vacuum Brazing is a process that creates high quality joints under temperatures from about 800°C to 1150°C in a vacuum atmosphere. This also allows for the joining of different materials like for example ceramic to steel.

Technology

Belt Furnace Brazing

Belt Furnace Brazing is a cost-efficient and continuous process that simultaneously applies brazing joints to relatively high volumes of components.

Technology

Induction brazing

Within Hauck Heat Treatment several plants are equipped to provide the induction brazing process.

Technology

Aluminium Brazing

Brazing of Aluminium is a complex process, at Hauck Heat Treatment we can offer several solutions for specific applications.
